Work on Technology That Protects What Matters
At SiXworks, we build secure digital solutions that support Defence and National Security missions. Our teams work on complex problems where reliability, security, and speed of innovation matter.
We’re looking for a Platform Engineer who enjoys solving difficult technical challenges and wants their work to have real operational impact.
What You’ll Do
As a Platform Engineer, you’ll lead the design and implementation of CI/CD pipelines, Kubernetes configuration, monitoring systems, repository management, automation, and other critical platform components. Collaborating closely with the Platform team, the Platform Engineer will ensure seamless integration of our offerings with the development team's requirements.
Your work may include:
- Configure Kubernetes environments to support scalable and resilient application deployments.
- Lead the design and construction of CI/CD pipelines to streamline the deployment process and enhance development efficiency.
- Support both on-premise and cloud platforms, ensuring consistency, reliability and maintainability through automation and Infrastructure as Code.
- Implement robust monitoring solutions to ensure the health and performance of platform services.
- Manage repository systems and version control to facilitate collaboration and code management.
- Drive automation initiatives to optimize workflow processes and reduce manual intervention.
- Collaborate with the Platform team to ensure alignment between platform capabilities and development team requirements.
- Provide guidance and oversight to the development team on best practices for utilising platform offerings effectively.
- Support initiatives related to platform maintainability, supportability, security, and scalability/performance as the platform evolves.
- Monitor industry trends and emerging technologies to continually enhance platform capabilities and practices.
What We’re Looking For
We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges. You don’t need to tick every box, but we’re particularly interested in people with skills/experience in:
- Bachelor's degree in Computer Science, Engineering, a related field or equivalent experience
- 5+ years of experience in Platform Engineering, Site Reliability Engineering, Platform Integration, or related roles.
- Strong proficiency in Kubernetes configuration and container orchestration techniques.
- Strong expertise in designing and implementing CI/CD pipelines using tools such as Jenkins, GitLab CI/CD, or similar.
- Experience with monitoring tools such as Prometheus, Grafana, or similar for infrastructure and application monitoring.
- Solid understanding of version control systems, preferably Git, and repository management practices.
- Proven track record of driving automation initiatives to improve operational efficiency and reliability.
- Excellent communication and collaboration skills, with the ability to interact effectively with cross-functional teams.
- Strong problem-solving skills and the ability to thrive in a fast-paced, dynamic environment.
- Experience with cloud platforms (e.g., AWS, Azure, Google Cloud) is a plus.
- Due to restrictions the candidate must be a UK National and eligible for SC clearance.
Just as important are curiosity, strong problem solving ability, and the motivation to continuously improve how technology is designed and delivered.
